Nitriding is a heat-treating process that diffuses nitrogen into the surface of a metal to create a case-hardened surface. A Nitrided Screw has a plethora of manufacturing capabilities. The applications of nitrided screws are injection molding, extrusion molding, and blow molding. By using high-quality grade nitriding steel, with 72 hours of nitriding process, the nitrided layer will help the screw to get better performance by being corrosion and abrasion-resistant. Nitrided screws have a very good wear resistance until the surface of the hardness is worn away.
